Remington’s Model 700 Stainless 5-R Threaded Barrel Part II

Handloading the 300 Winchester Magnum

I’m not sure when it all began. Might have been in the 70s and a fateful  trip with our children to Disney World. More specifically, the “It’s a Small World” exhibit. My wife and I share much in common, however, in some ways we significantly differ. I stepped out of the car at the end of the ride thinking my head would explode over the repetition of the “It’s a Small World” song and sappy one world, “Let’s all hold hands” communist tripe. My wife came away with the notion she would set out to reduce the size of all that comprise the physical world. Our perspectives tempered our experiences; my recent completion of military service and B-52 bomb wing rotations to Southeast Asia, my wife being vertically challenged and believing anything taller attempts to bully or suppress her energetic Irish being. I grumble, but she acts. Example? Sure.

This past weekend, one of my wife’s dwarf pear trees defected from her army of all things small when It began to grow quite rapidly, vertically, almost majestically. While I was busy cleaning up the tree line, pruning low branches and brush and tossing them in the chipper, my wife picked up the lopper and indicated she was going to prune the pear tree. That should have set off an alarm, but I was distracted. A few minutes later, I glanced over to see her trimming off dead branches and watersprouts, letting them fall into neat little piles beneath the tree. Ten minutes later, I heard the chainsaw roar to life and looked over just in time to see B movie grade fruit tree carnage. Bark, sawdust and pears flying everywhere if for only a shocking, intense brief moment. Then silence.

She turned and faced the rest of the fruit trees with a smile on her face, she is a very sweet woman, and they all seemed to hunker down just a bit to avoid standing out. Me too. OK, maybe my imagination is coloring my perception a bit. Yes, the tree was rotting from the inside out and carpenter ants did pour out of the stump. And, yes, the trunk did fall apart when lifted, but it was the way she said, “There. Doesn’t that look better?”.

Bullets were selected that I felt would best represent the Remington Model 700 Stainless R-5 / 300 Winchester Magnum combination’s potential, They are all medium to big game suitable, up to 1500 lbs… deer through elk and moose. With the exception of the Nosler Partition and Hot-Cor, they are all secant ogive, VLD designs.

Warning: Bullet selections are specific, and loads are not valid with substitutions of different bullets of the same weight. Variations in bullet length will alter net case capacity,  pressure and velocity. Primer selection is specific and primer types are not interchangeable. These are maximum loads in my firearms and may be excessive in others. All loads should be reduced by 5% as a starting point for development where cartridges have greater than 40 grains in capacity and 10% for cartridges with less than 40 grain capacity following safe handloading practices as represented in established mainstream reloading manuals. Presentation of these loads does not constitute a solicitation for their use, nor a recommendation.

Notes… I have none

A comment on one of my handloading articles said, “He doesn’t provide any notes”. I couldn’t help but think, “What notes?”. Yes, I think aloud sometimes and use quotation marks instead of drawing little puffy thought bubbles. Processes are defined in mainstream reloading manuals, or evolve in the, hopefully, full fingered hands of experienced handloaders. Yes, clean casings, trim to length, deburr, inside/outside case mouth, inspect for flaws and mutated cases…. None of the loads are compressed to any significant degree. I did not roll crimp, jelly or otherwise, nor did I cheat and use a Lee collet crimper and pretend these bullets had cannelures. I did use VLD seater plugs , but I felt everyone should have the experience of at least one mangled VLD bullet before realizing a standard plug does not provide sufficient surface area contact to prevent bullets deformation when seating.

No pressure is given because none was recorded; no 300 Win mag test barrel for the universal receiver and no firearm wired for strain. Instead all of the loads are mainstream component manufacturers derivative with maybe a little more, or a little less charge as dictated by accuracy, recorded velocity or: pie faced primers, sticky cases, arm wrestling bolt opening, excessive case head expansion, etc. Powder selection was what yielded the best accuracy, which means digging through 6 – 10 to get 1, which is actually about par for the course. I have to laugh when someone proudly tinkers with QuickLOAD then publishes his tinkering methods calculated pressure as though it data. I can’t even get duplicate data out of a piezo transducer set up and two different test barrels for the same cartridge.

No notes, the warning notice ahead of the data is for real. Handload long enough and you’ll be able to hear and feel excess chamber pressure when shooting.

Conclusions?

The Remington Model 700 Stainless 5-R threaded barrel made for terrific range days and it is always enjoyable handloading the 300 Winchester Magnum. I did shoot some 200+ yard targets, distance not diameter, but not enough to publish as formal results. Staying under an inch at 200 yards was not a problem. Yes, MOA results are supposed to extend as an angular projection to more distant targets. However,, sometimes a shooter’s aim grows more critical as targets are pushed out. I am sure there is some fourteen year old kid popping 2″ targets at 1,000 yards as I write this, so please don’t take my performance as the Remington’s potential as my early potential with the Remington. Not exactly in need of a spoiler alert; Remington continues to make outstanding rifles.
